Webquest 1

I. What were the three leading hypotheses on the formation of the Moon before the Apollo missions?
The three hypothesis are as follows:
1. The moon is a sister world that formed in orbit around the Earth as the Earth formed.
2.The moon was formed in the universe where there was little iron then the iron was captured into the orbit around the Earth.
3. The planet Earth spun so fast that it spun off the Moon.
II. Why were they rejected in the end?
These ideas failed because there were not explanations for these hypothesis.


"Formation of the moon"
1. What formation theory is presented in this video?
The meteor impact theory was presented.
2.What is anorthosite, and how/when did it form?
Anorthosite is chystaline rock. It is an ancient material that is made of sparkling crystals.
3.Why is anorthosite so important?
Anorthosite will provide history with its age and orgin.
It is important because it can be studied to tell the age, orgin of the moon. It is the sample of the moon's crust. It is 41/2 billion years old.
4. What evidence do the scientist in the video give to support their new theory?
Earth was struck by a moon sized asteroid 4.5 billion years ago.  Debris coalesced to form the moon. This new theory was developed by William Hartmann.
5. Which Apollo mission provided this evidence?
Apolllo 15
6.Why is it so important for us to understand the Moon's composition, structure and history?
The moon is very important to our planet.  The Moon moderates temperature, liquid water, tides, and life itself.
